Figure 3-1 — Three remote control options

1

Using the projector’s IR remote

 — For a projector with variable

audio outputs, use the projector’s IR remote to control the
projector’s volume, which effectively controls the MPA’s
volume.

2

Extron VCM 100 or mute controller

 — For a projector without

variable audio outputs, or for a system designed to control MPA
volume directly, use a 10k ohm potentiometer to control the
MPA directly via the remote port on the MPA.

3

Using a MediaLink™ Controller

 — For a projector with

variable audio output, use a MediaLink controller to control the
projector’s volume via RS-232 or the projector’s IR remote to
effectively control the MPA volume.
